The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Two thousand five hundred plants, representing 232 diverse populations of Cannabis, were grown under standard conditions in a garden, scored for 47 attributes, and the data used in a numerical taxonomic study of variation. Groups of interest included "nonintoxicant" and "semi-intoxicant" populations (collectively referable to C. sativa), "intoxicant" populations (sometimes called C. indica), fiber and oil cultivars (referable to C. sativa), "wild" populations (sometimes called C. ruderalis), and plants either containing or not containing cannabigerol monomethyl ether. Clustering methodology revealed only a limited tendency for the populations to separate into the above groupings. However, canonical analysis (equally weighted multiple discriminant analysis) of morphological characteristics only proved highly successful in delineating the groups. The analysis resulting from the comparison of wild and cultivated populations when applied to a large sample of populations failed to suggest two discrete groupings, and it is consequently concluded that wild and cultivated populations intergrade so greatly as to preclude recognition of wild plants as a separate species (the so-called C. ruderalis). Those morphological characteristics that successfully distinguish intoxicant populations from other populations in material raised under standardized garden conditions were sufficiently variable to suggest that the intoxicant potential of plants collected in nature cannot be reliably distinguished by morphology; consequently it is judged that there are no grounds for distinguishing intoxicant plants (the so-called C. indica) as a separate species. It is concluded that all plants of Cannabis are assignable to one species, C. sativa.
